DTA ECU Programming

[Robert Q]

I'm in the process of replacing the existing ECU (MBE 912V3)on my VX 2.0L 16V, which has had reliability problems recently (not always providing a spark) with a new DTA E48.

 

The wiring I should be able to cope with as I have almost finished modifying the original loom.

 

I have never programmed an ECU before and am a bit dubious about it. I overheard someone say you can fit a lambda sensor and map the engine closed loop without visiting a rolling road.

 

Does anyone have experience of doing this and did it work out OK ?

 

Thanks in advance for any tips.

 

Regards

Robert

 

P.S. Would it be feasible to translate my MBE map into DTA format ?

Nice theory, in practice it's not feasible. You might be able to use it to fine tune a map that's already close. Closed-loop mapping is a possibly useful aid to mapping on an engine dyno.

If you can extract the maps from the MBE in some sort of text format, and you know the distribution of the load & rpm sites and the injector duration scaling factors then it should be possible (but I'm not volunteering...).

Robert,

 

MBE will extract the map to an MBE map file.

 

You can then get a copy of easimap and load and record each of the values.

 

you will then have to manually enter these into the DTA.

 

SFAIK there is no interchangeable flat file format unless DTA write an import script for the maps from an MBE unit.

Thanks Mike and Arnie for your advice, looks like whatever it's not that straight forward - I guess these things never are.

 

Best Regards
